Description

  The present invention relates to a metal plate shelf. In particular, the present invention relates to a shelf made of a metal plate, a storage, and a shelf plate used for a wagon or the like that is movable by attaching casters to the lower part thereof.

  The metal plate shelf is generally called a steel shelf. The metal plate shelf is formed by bending a metal plate to form a support column and a shelf plate and assembling them to form a shelf. In the metal plate storage, a metal plate shelf is attached in a box-like body with a door made by bending a metal plate so as to be detachable and changeable. In addition, the metal plate wagon can be moved by attaching a caster to the lower side of the column constituting the shelf.

  Metal plate shelves are used to store and store products and tools in factories, for example, and metal plate vaults are used to store documents and tools, and metal wagons are used to store products and tools in factories and canteens, for example. Used to carry food.

  Of these, the storage is as described above, so that the shelves can be detachably and rearranged, so the shelves need to be lightweight and bend when a heavy object is placed on them. Should not be.

  Of these shelves, for example, as disclosed in Japanese Patent No. 3437988, a plurality of shelves and four columns that support the shelves at four corners are configured. This structure occupies a large volume when assembled, but becomes a small volume when disassembled. Therefore, it is assembled and disassembled for convenience of storage and transportation. Therefore, the shelf board is required to be lightweight. Moreover, as a shelf board, it must not bend when putting a product or a tool like a storage.

  The same applies to the wagon, and the shelf board used for the wagon is required to be light and less bent.

As a result, the shelf plates used for these were bent into a shallow box consisting of a rectangular plate bottom and four side walls standing on the periphery of the bottom.
Japanese Patent No. 3437988

  Shallow box-shaped shelf made of metal plate, when attached with the side wall facing up, becomes a shelf plate with anti-spilling on the four sides, and conversely, when attached with the side wall facing down, there is no anti-spilling on the four sides The whole can be used as a flat shelf. Shelves with spill stoppers on all sides are convenient for placing small items, but when loading or unloading heavy objects, the spill stoppers are an inconvenience, and there is no spill prevention. A shelf board is convenient for placing heavy objects. Therefore, it is said that it is convenient that the assembly type metal plate shelf can be used in two ways, one with and without spilling, with the front and back being overturned. The same applies to wagons and storages.

  However, the above-described conventional shelf simply formed into a shallow box shape has a drawback that it is greatly bent when it is used where the distance between the fulcrums is long or a heavy object is placed on the shelf. Therefore, it is necessary to reduce this deflection as much as possible.

When the shelf board is made of a synthetic resin, it is known that the shelf board is hollow to reduce the deflection of the shelf board and is formed into a structure in which reinforcing ribs are provided inside. In this case, the reinforcing rib is a strip having a width in the thickness direction of the shelf, and is connected to the outer shell of the shelf on both sides of the width and extends in the longitudinal direction of the shelf. Such shelves are described in, for example, Japanese Patent Application Laid-Open Nos. 8-80226 and 8-294422. However, when the shelf board is made of metal, it is not easy to form the shelf board into such a structure.

One attempt to reinforce a metal plate shelf is described in JP-A-11-266938. This publication discloses a special means for locking the reinforcement to the shelf rather than to fix the reinforcement to the shelf. The locking means is provided with a cylindrical part protruding to the back side on the shelf plate, a through hole is provided in the reinforcing material, the cylindrical part is inserted into the through hole, and the tip of the cylindrical part is bent outward and locked. It is to let you. In this publication, as a reinforcing material, a band-shaped metal plate having a Z-shaped cross section is fixed to both ends in the width direction of a shelf plate, and a band-shaped metal plate having a plate-shaped cross section is attached to the center in the width direction. Has a space where nothing is attached. Therefore, this shelf has a large step in the width direction on the back surface. Therefore, this shelf board cannot be used with the back side up.
Japanese Patent Laid-Open No. 11-266938

  By reversing the front and back, the present invention can be used as a shelf board with spillage prevention and can also be used as a shelf board without spillage prevention, while reinforcing the shelf board while retaining the convenience of the shelf board. It is intended to provide a shelf board with less.

  In order to solve the above-mentioned problems, the present invention uses a rectangular box-shaped shelf board having a right-angled quadrilateral shape as a main body, and attempts to reduce the deflection of the shelf board body by attaching a reinforcing body thereto. In short, this invention is intended to reinforce the shelf main body by creating a plane corresponding to the raised bottom of the box by a reinforcing body inside the box-shaped shelf. For this purpose, the present invention prepares a plurality of structures having a flat top plate and legs standing up from now on as reinforcing bodies, and makes the heights of the legs of each reinforcing body equal to each other, and also has a shallow box shape. The height of the side wall of the shelf is kept lower, and such a reinforcing body is laid in a box-shaped shelf, the reinforcement is fixed to the box-shaped shelf, and the box is formed by adjoining a plurality of top plates. The main point is to form a parallel plane corresponding to the raised bottom in the shelf board.

  That is, the present invention is a shallow box-shaped shelf board body made of a metal plate comprising a bottom of a right-angled quadrilateral and four side walls standing on the periphery of the bottom, and a plurality of metal plates attached to the inside thereof. Each reinforcing body is provided with a flat top plate and legs that stand up from the top plate, and the legs are equal in height to each other and less than the height of the side wall of the main body. The metal is characterized in that the tip of the abutment is in contact with the bottom of the main body, the top plate as a whole covers the bottom of the main body without gaps to form a flat surface, and the reinforcing body is fixed to the main body. A board shelf board is provided.

  As the metal that can be used in the present invention, aluminum, copper, and the like can be used, but iron and stainless steel are preferable. As the thickness of the metal plate, a thickness within the range that has been used so far to constitute a steel shelf can be used. In particular, as a shelf main body, a shallow box-shaped shelf that has been used so far can be used as it is.

  The reinforcing body is preferably made by bending a metal plate. In particular, it is preferable that the leg portion of the reinforcing body is formed by bending an extension portion of the top plate. In the present invention, a fixing portion is provided as necessary, but it is preferable that the fixing portion is also formed by bending an extension portion of the top plate.

  In order to fix the reinforcing body to the main body, adhesion by resin or metal welding can be used. For the adhesion by the resin, it is preferable to apply a thermosetting resin, for example, an epoxy resin to the whole or part of the leg portion and adhere it to the side wall of the main body. In the case of metal welding, it is preferable to attach a fixing portion to the reinforcing body and spot weld a part of the fixing portion to the main body side wall.

  A metal plate shelf according to the present invention is a conventionally used shelf plate, that is, a shallow box-shaped shelf made of a metal plate comprising a bottom of a right-angled quadrilateral and four side walls standing on the periphery of the bottom. Is a shelf board main body, and a plurality of metal plate reinforcing bodies are used, and the reinforcing body is provided in the main body. The reinforcement body includes a flat top plate and legs that stand up from the top plate, and the height of the legs is equal to each other and equal to or less than the height of the side wall of the main body. When laid down, the top plate of the reinforcement body forms a flat surface parallel to the bottom of the main body within the main body. The shelf board obtained by fixing the reinforcing body to the main body in this state has a structure in which a raised bottom is formed inside. Therefore, this shelf board is reinforced by the reinforcing body and is less bent.

  In general, a shelf board with a spill stopper is convenient when placing small items, but when placing heavy objects, the spill stopper prevents the spill from being obstructed, so a shelf board without a spill stopper is required. In such a case, the shelf board of the present invention can be used as a shelf board without spillage when the bottom of the shelf board body is turned up, and can be used as a shelf board with spillage prevention by turning it over. It exactly meets the above needs. In this respect, the present invention provides a great practical advantage.

  An embodiment of the present invention will be described with reference to the drawings as follows.

  FIG. 1 is a partially cutaway perspective view of a metal plate shelf according to the present invention. FIG. 2 is an enlarged exploded perspective view, partly cut away, of the metal plate shelf shown in FIG. FIG. 3 is a partially cutaway perspective view of another metal plate shelf according to the present invention. FIG. 4 and FIG. 5 are partially exploded enlarged perspective views of still another metal plate shelf according to the present invention. FIG. 6 is a partially cutaway perspective view of still another reinforcing body that can be used in the present invention.

  In FIG. 1, a metal plate shelf A according to the present invention is made by spreading reinforcing bodies 2 in a shelf board body 1 without gaps. The shelf main body 1 is a shallow box-shaped body composed of a rectangular base 11 and four side walls 12, 13, 14, and 15 that stand on the periphery of the bottom 11. The four corners may be in a state in which there is no gap between the ends of the side walls, but a gap may be formed between the ends of the side walls without being welded but only in proximity to each other. The shelf body 1 is conventionally used as a shelf board.

  In FIG. 1, each reinforcing body 2 includes a flat top plate 21, leg portions 22 formed by extending an extension portion of the top plate 21 to the bottom 11, and an extension portion of the top plate 21. And a fixing portion 23 made to stand up. The heights of the leg portions 22 of the reinforcing bodies are equal to each other, and are smaller than the heights of the side walls 12 to 15 of the main body 1. In particular, the height of the leg portion 22 is set so that the distal end of the fixing portion 23 does not protrude from the distal ends of the side walls 12-15. The leg portion 22 is provided along at least two opposite sides of the four sides of the top plate 21.

  The reinforcing body 2 is placed in the box of the main body 1 with the leg portion 22 facing the bottom 11 of the main body 1, and the tip of the leg portion 22 is attached to the bottom 11. In this way, the reinforcing body 2 is laid out inside the main body 1 so that the top plate 21 as a whole covers the bottom 11 of the main body 1 without a gap. Then, the top plates 21 are close to each other and form a flat surface having a uniform height parallel to the bottom 11. In this state, the fixing portion 23 of the reinforcing body 2 is fixed to the side walls 13 and 15 of the main body 1. In this way, the shelf board A according to the present invention is produced.

  FIG. 2 shows the details of the structure of the main body 1 and the reinforcing body 2 put in it when the shelf A of FIG. 1 is constructed. In a direction in which the side wall 12 of the short side of the main body 1 extends, the reinforcing body 2 includes a leg portion 22 that extends over almost the entire length of the side of the top plate 21. The leg 22 is attached along a pair of opposing sides of the top plate 21. The legs 22 are uniform in height and equal to each other. The reinforcing body 2 includes a fixing portion 23 extending substantially over the entire length in the direction in which the side wall 13 having the long side of the main body 1 extends.

  When the reinforcing body 2 is placed in the main body 1 and the tip of the leg portion 22 comes into contact with the bottom 11, the top plate 21 becomes a plane parallel to the bottom 11. At this time, the front end of the fixing portion 23 has the same height as the front end of the side wall 13 or the like, or is positioned lower than the front end of the side wall 13. The fixing part 23 is brought into close contact with the side wall 13. In this way, the fixing portion 23 is bonded or spot welded to the side wall 13, and the reinforcing body 2 is fixed in the main body 1.

  The shelf A in FIG. 1 is an example in which a plurality of reinforcing bodies 2 are arranged in the longitudinal direction of the main body 1, but the shelf B in FIG. 3 has a plurality of reinforcing bodies 2 in the width direction of the main body 1. It is an example that is arranged. In the shelf board according to the present invention, as shown in FIG. 3, the reinforcing body 2 may be provided so as to penetrate in the longitudinal direction of the main body 1. The reinforcing body 2 shown in FIG. 3 includes leg portions 22 along the longitudinal side of the top plate 21, and includes a fixing portion 23 along the side in the width direction. The top plate 21 as a whole covers the bottom 11 without a gap, and constitutes a flat surface parallel to the bottom 11. Moreover, the fixing | fixed part 23 has covered the inner surface of the side walls 12 and 14 without gap in the width direction.

  The shelf board C shown in FIG. 4 is an example in which the reinforcing body is formed in a shallow box shape. In the present invention, such a reinforcing body can be used. In the reinforcing body 2 shown in FIG. 4, the extended portions of the four sides of the top plate 21 are erected vertically in the same direction, and both constitute leg portions 22. The leg 22 is fixed to the side wall of the main body by bonding.

  FIG. 5 shows an example in which a fixing portion 23 is further attached to the reinforcing body of FIG. The fixing part has a notch in a part of the leg part 22 in contact with the side wall 13, and a part of the fixing part is vertically raised to the opposite side to form a fixing part 23. Although not shown in FIG. 5, a fixing portion similar to the fixing portion 23 is also formed on the leg portion in contact with the other side wall of the main body facing the side wall 13. The fixing portion 23 thus made may be fixed to the side wall by spot welding, and the reinforcing body 2 may be fixed to the main body 1.

  In the reinforcing body 2 shown in FIGS. 1 to 5, the tip end of the leg portion 22 is standing from the top plate 21. However, as shown in FIG. 6, the leg portion 22 may be bent further inward, and the bent tip portion 24 may form a plane parallel to the top plate 21. The outer surface of the distal end portion 24 comes into close contact with the bottom 11 when the reinforcing body 2 is installed in the main body 1. The reinforcement body 2 shown in FIG. 6 is less bent in the direction of the arrow X than the reinforcement body 2 shown in FIG.

  As shown in FIGS. 2 and 6, in the reinforcing body in which the fixing portion 23 is raised from the top plate 21 on the opposite side to the leg portion 22, the fixing portion 23 extends from one end of the top plate 21 to the end. It is preferable to extend to. This is because such fixing parts 23 are arranged without gaps on the side wall of the main body, have a good appearance, can be firmly fixed, and have a great reinforcing effect. The leg portion 22 may also extend from end to end on the other side of the top plate 21, but may be cut and disappeared until reaching the end as shown in FIG.

  In the shelf plate according to the present invention, the main body and the reinforcing body are integrally fixed, and the bottom of the main body and the top plate of the reinforcing body extend in parallel with each other, and a gap is formed therebetween, It is less bent and therefore lighter and less bent. In addition, the top plate of each reinforcing body is flush with the inside of the main body and extends parallel to the bottom of the main body, so it can be used as a shelf board with spillage when the top plate is up, and conversely When the board is down, it can be used as a shelf board without spillage.

It is a partially cutaway perspective view of a metal plate shelf according to the present invention. FIG. 2 is an enlarged exploded perspective view of a part of the metal plate shelf shown in FIG. 1. It is a partially cutaway perspective view of another metal plate shelf according to the present invention. It is a partially cutaway exploded perspective view of still another metal plate shelf according to the present invention. It is a partially cutaway exploded perspective view of still another metal plate shelf according to the present invention. It is a partially cutaway perspective view of still another reinforcing body that can be used in the present invention.
